Yeah, part of the frustration with Vlad is that he's SO CLOSE to being great.
It's not like he got to MLB and, whelp, it became clear that he can't hit elite MLB pitches. That type of obvious failure is almost easier to accept. If Jo Adell never hits MLB pitching it will kind of be the fulfillment of what was always an obvious risk in his profile.
But Vlad can put the bat on nearly any pitch, strikeouts aren't a problem, and he can hit the ball 120 mph and 500 feet when he connects correctly. The mechanical flaws that have him hitting the ball 110+ mph directly into the dirt are just infuriating. It's so hard to figure out why it's the case, why it hasn't been fixed, whether it is a permanent or short term problem.
You'd almost prefer a prospect to just fail, rather than tease you with their potential forever! (not really)
